I recently purchased my 2006 IS350, LOVE IT, but the other day i hit a nasty pot hole and imidiatly the TPMS CHECK SYSTEM came on the info screen along with the triangle ! and the actual tire light in the bottom right corner of the cluster. I have taken it to Discount tire and they tested all of the wheel sensors, they are good. The tech said it could have knocked something loose on the ECU. Before i take it to the stealership/dealership does ANYONE know a possible fix and where the ECUs are located. I have also read somewhere there is a wire behind the radio that could get "pinched".
Also the air bag light is on in the bottom right of the cluster(has been since i purchased the car) any idea what the fix could be for that? THANKS!

I removed the radio and found that the TPMS ecu harness had come loose. I reattached it and zip tied the harness to the ECU. Now on to the air bag light....

 

Codes please...

 

I have my ScanGauge hooked up and it's not reading any codes

 

check your tires pressure for leak, the wheel that hit the pothole might be damaged the TPMS sensor, TPMS is inflation for the wheel, they will not give codes it's not a Check Engine, Discount tires said it knocked the ECU ? my opinion, your TPMS sensor might be broken. if ECU damaged it won't give u the warning light. check tires pressure 1st and then sensor.

 

Bad TPMS ECU still give out the flat tire warning light. The TPMS ECU is located on top of the Navigation screen.
When you turn on the car, if you see warning light blinking then either bad TPMS (more chance) or UCE itself.
If it be soiled then check air pressure again. I would think your TPMS is damage

 

The wheel is slightly bent at the flange but it has held the same air pressure for the past 3 days.
Discount tire put a reader by each tpms sensor and each sensor responded.
I do not have navigation, would the ECU be in the same place?
when I turn on the car the pressure light in the right corner blinks for a min then stays solid. The check system light comes on and stays solid.

 

Have you tried resetting the TPMS system?

 

Ive tried but I'm not sure if I was doing it right. I found a few treads on here but no 2 were exactly the same process.....
